428-454 | 8.78e-03 | |||
PBS lyase HEAT-like repeat; This family contains a short bi-helical repeat that is related to pfam02985. Cyanobacteria and red algae harvest light energy using macromolecular complexes known as phycobilisomes (PBS), peripherally attached to the photosynthetic membrane. The major components of PBS are the phycobiliproteins. These heterodimeric proteins are covalently attached to phycobilins: open-chain tetrapyrrole chromophores, which function as the photosynthetic light-harvesting pigments. Phycobiliproteins differ in sequence and in the nature and number of attached phycobilins to each of their subunits. This family includes the lyase enzymes that specifically attach particular phycobilins to apophycobiliprotein subunits. The most comprehensively studied of these is the CpcE/F lyase, which attaches phycocyanobilin (PCB) to the alpha subunit of apophycocyanin. Similarly, MpeU/V attaches phycoerythrobilin to phycoerythrin II, while CpeY/Z is thought to be involved in phycoerythrobilin (PEB) attachment to phycoerythrin (PE) I (PEs I and II differ in sequence and in the number of attached molecules of PEB: PE I has five, PE II has six). All the reactions of the above lyases involve an apoprotein cysteine SH addition to a terminal delta 3,3'-double bond. Such a reaction is not possible in the case of phycoviolobilin (PVB), the phycobilin of alpha-phycoerythrocyanin (alpha-PEC). It is thought that in this case, PCB, not PVB, is first added to apo-alpha-PEC, and is then isomerized to PVB. The addition reaction has been shown to occur in the presence of either of the components of alpha-PEC-PVB lyase PecE or PecF (or both). The isomerization reaction occurs only when both PecE and PecF components are present, i.e. the PecE/F phycobiliprotein lyase is also a phycobilin isomerase. Another member of this family is the NblB protein, whose similarity to the phycobiliprotein lyases was previously noted. This constitutively expressed protein is not known to have any lyase activity. It is thought to be involved in the coordination of PBS degradation with environmental nutrient limitation. It has been suggested that the similarity of NblB to the phycobiliprotein lyases is due to the ability to bind tetrapyrrole phycobilins via the common repeated motif. : Pssm-ID: 308641 [Multi-domain] Cd Length: 27 Bit Score: 34.38 E-value: 8.78e-03

Sister chromatid cohesion protein PDS5; Pds5 plays a crucial role in sister chromatid cohesion. Together with WapI and Scc3, it is involved in the release of the cohesin complex from chromosomes during S phase. The core of the cohesin complex consists of a coiled-coiled heterodimer of Smc1 and Smc30, together with Scc1 (also called kleisin). Pds5 interacts with Scc1 via a conserved patch on the surface of its heat repeats. Pds5 also promotes the acetylation of Smc3 that protects cohesin from releasing activity in G2 phase.

Together with WapI and Scc3, it is involved in the release of the cohesin complex from chromosomes during S phase. The core of the cohesin complex consists of a coiled-coiled heterodimer of Smc1 and Smc30, together with Scc1 (also called kleisin). Pds5 interacts with Scc1 via a conserved patch on the surface of its heat repeats. Pds5 also promotes the acetylation of Smc3 that protects cohesin from releasing activity in G2 phase.

PBS lyase HEAT-like repeat; This family contains a short bi-helical repeat that is related to pfam02985. Cyanobacteria and red algae harvest light energy using macromolecular complexes known as phycobilisomes (PBS), peripherally attached to the photosynthetic membrane. The major components of PBS are the phycobiliproteins. These heterodimeric proteins are covalently attached to phycobilins: open-chain tetrapyrrole chromophores, which function as the photosynthetic light-harvesting pigments. Phycobiliproteins differ in sequence and in the nature and number of attached phycobilins to each of their subunits. This family includes the lyase enzymes that specifically attach particular phycobilins to apophycobiliprotein subunits. The most comprehensively studied of these is the CpcE/F lyase, which attaches phycocyanobilin (PCB) to the alpha subunit of apophycocyanin. Similarly, MpeU/V attaches phycoerythrobilin to phycoerythrin II, while CpeY/Z is thought to be involved in phycoerythrobilin (PEB) attachment to phycoerythrin (PE) I (PEs I and II differ in sequence and in the number of attached molecules of PEB: PE I has five, PE II has six). All the reactions of the above lyases involve an apoprotein cysteine SH addition to a terminal delta 3,3'-double bond. Such a reaction is not possible in the case of phycoviolobilin (PVB), the phycobilin of alpha-phycoerythrocyanin (alpha-PEC). It is thought that in this case, PCB, not PVB, is first added to apo-alpha-PEC, and is then isomerized to PVB. The addition reaction has been shown to occur in the presence of either of the components of alpha-PEC-PVB lyase PecE or PecF (or both). The isomerization reaction occurs only when both PecE and PecF components are present, i.e. the PecE/F phycobiliprotein lyase is also a phycobilin isomerase. Another member of this family is the NblB protein, whose similarity to the phycobiliprotein lyases was previously noted. This constitutively expressed protein is not known to have any lyase activity. It is thought to be involved in the coordination of PBS degradation with environmental nutrient limitation. It has been suggested that the similarity of NblB to the phycobiliprotein lyases is due to the ability to bind tetrapyrrole phycobilins via the common repeated motif.

Cyanobacteria and red algae harvest light energy using macromolecular complexes known as phycobilisomes (PBS), peripherally attached to the photosynthetic membrane. The major components of PBS are the phycobiliproteins. These heterodimeric proteins are covalently attached to phycobilins: open-chain tetrapyrrole chromophores, which function as the photosynthetic light-harvesting pigments. Phycobiliproteins differ in sequence and in the nature and number of attached phycobilins to each of their subunits. This family includes the lyase enzymes that specifically attach particular phycobilins to apophycobiliprotein subunits. The most comprehensively studied of these is the CpcE/F lyase, which attaches phycocyanobilin (PCB) to the alpha subunit of apophycocyanin. Similarly, MpeU/V attaches phycoerythrobilin to phycoerythrin II, while CpeY/Z is thought to be involved in phycoerythrobilin (PEB) attachment to phycoerythrin (PE) I (PEs I and II differ in sequence and in the number of attached molecules of PEB: PE I has five, PE II has six). All the reactions of the above lyases involve an apoprotein cysteine SH addition to a terminal delta 3,3'-double bond. Such a reaction is not possible in the case of phycoviolobilin (PVB), the phycobilin of alpha-phycoerythrocyanin (alpha-PEC). It is thought that in this case, PCB, not PVB, is first added to apo-alpha-PEC, and is then isomerized to PVB. The addition reaction has been shown to occur in the presence of either of the components of alpha-PEC-PVB lyase PecE or PecF (or both). The isomerization reaction occurs only when both PecE and PecF components are present, i.e. the PecE/F phycobiliprotein lyase is also a phycobilin isomerase. Another member of this family is the NblB protein, whose similarity to the phycobiliprotein lyases was previously noted. This constitutively expressed protein is not known to have any lyase activity. It is thought to be involved in the coordination of PBS degradation with environmental nutrient limitation. It has been suggested that the similarity of NblB to the phycobiliprotein lyases is due to the ability to bind tetrapyrrole phycobilins via the common repeated motif.

PBS lyase HEAT-like repeat; This family contains a short bi-helical repeat that is related to pfam02985. Cyanobacteria and red algae harvest light energy using macromolecular complexes known as phycobilisomes (PBS), peripherally attached to the photosynthetic membrane. The major components of PBS are the phycobiliproteins. These heterodimeric proteins are covalently attached to phycobilins: open-chain tetrapyrrole chromophores, which function as the photosynthetic light-harvesting pigments. Phycobiliproteins differ in sequence and in the nature and number of attached phycobilins to each of their subunits. This family includes the lyase enzymes that specifically attach particular phycobilins to apophycobiliprotein subunits. The most comprehensively studied of these is the CpcE/F lyase, which attaches phycocyanobilin (PCB) to the alpha subunit of apophycocyanin. Similarly, MpeU/V attaches phycoerythrobilin to phycoerythrin II, while CpeY/Z is thought to be involved in phycoerythrobilin (PEB) attachment to phycoerythrin (PE) I (PEs I and II differ in sequence and in the number of attached molecules of PEB: PE I has five, PE II has six). All the reactions of the above lyases involve an apoprotein cysteine SH addition to a terminal delta 3,3'-double bond. Such a reaction is not possible in the case of phycoviolobilin (PVB), the phycobilin of alpha-phycoerythrocyanin (alpha-PEC). It is thought that in this case, PCB, not PVB, is first added to apo-alpha-PEC, and is then isomerized to PVB. The addition reaction has been shown to occur in the presence of either of the components of alpha-PEC-PVB lyase PecE or PecF (or both). The isomerization reaction occurs only when both PecE and PecF components are present, i.e. the PecE/F phycobiliprotein lyase is also a phycobilin isomerase. Another member of this family is the NblB protein, whose similarity to the phycobiliprotein lyases was previously noted. This constitutively expressed protein is not known to have any lyase activity. It is thought to be involved in the coordination of PBS degradation with environmental nutrient limitation. It has been suggested that the similarity of NblB to the phycobiliprotein lyases is due to the ability to bind tetrapyrrole phycobilins via the common repeated motif.

HEAT-like repeat; The HEAT repeat family is related to armadillo/beta-catenin-like repeats (see pfam00514). These EZ repeats are found in subunits of cyanobacterial phycocyanin lyase and other proteins and probably carry out a scaffolding role.
